> Which cable cross section is recommended to the detection loops?

You should always use shielded cable of the type appropriate for fire detection installations. Please note that cable types are also regulated by local authorities/ standards.As a rule of thumb you should use:

a) 0,8 mm2 for loop lengths up to 500 mb) 1.0 mm2 for loop lengths up to 800 mc) 1.5 mm2 for loop lengths up to 1200md) 2.5 mm2 for loop lengths up to 1500 m

The lengths specified include return to the main panel.

> What is the maximum length for a detection loop in a GFE analog panel?

The maximum recommended length is approximately 1200 m, but this value depends largely on the cable cross section and the load of the devices in that loop. We developed the GFE Loop Calculator software where it is possible to verify if your system has an appropriate loop length.
